MIPS: ath79: reduce ARCH_DMA_MINALIGN
Currently, ath79 SoCs use the default ARCH_DMA_MINALIGN value of 128
bytes defined in mach-generic. This is excessive for these platforms
and leads to significant memory waste in kmalloc.
Override ARCH_DMA_MINALIGN to use L1_CACHE_BYTES, which is 32 bytes for
ath79 SoCs.
